An Evidence-Based Update on Anticholinergic Use for Drug-Induced Movement Disorders

This can involve living at a detox facility or hospital for several weeks, where you can receive constant medical monitoring and psychological support. However, that doesn’t necessarily mean you will require inpatient care. Most people do okay with tapering their benzodiazepines at home with the help of their primary care doctor or heroin addiction psychiatrist.

Comparison 1. Anticholinergic medications versus other compounds.

This 12-week study employed a double-blind crossover design on 39 adult in-patients selected from a total hospital population of 620. The Colombia Scale was used to determine extrapyramidal side effects (EPS). All patients were stabilised prior to the study on benztropine mesylate 2 mg b.i.d., and gradual withdrawal was employed. Benztropine withdrawal produced a significant increase in overall EPS scores. Ten patients (26%) required reinstatement of benztropine while on placebo.

  • This would take a further weeks, so the total withdrawal might last weeks.
  • Only one study provided useable data on adverse events as a result of medication (Bucci 1971).
  • In comparison, the control group only showed a weighted mean of 0.11 (95% CI, 0.03–0.19) after continuation of oral antipsychotic treatment.

Data collection and analysis

Moreover two cases of a severe cholinergic rebound syndrome after a clozapine-olanzapine switch in schizophrenic patients were reported 13. This may be somehow surprising since olanzapine is also considered to have a significant affinity for muscarinic receptors. However works comparing in vitro affinity on muscarinic receptors of atypical antipsychotics showed that the anticholinergic activity of olanzapine was less pronounced than the clozapine anticholinergic activity by a factor ten 14. This difference as well as benztropine withdrawal administered doses may have accounted for the observed withdrawal syndromes. There is insufficient evidence for changing antipsychotic regimens or discontinuing antipsychotics to treat TD 63–65.

Data Availability Statement

The odds ratios from the individual trials were combined using appropriate methods of meta‐analysis. When overall results were significant the number needed to treat to produce (or prevent) one outcome was calculated by combining the overall odds ratio with an estimate of the https://larkmagazine.com/nonallergic-rhinitis-symptoms-causes-4/ prevalence of the event in the control groups of the trials. The reviewers independently evaluated the quality of all included trials. A rating was given for each trial based on the three quality categories as described in the Cochrane Collaboration Handbook (Mulrow 1999).

Due to similarity in symptoms, akathisia may be misdiagnosed as anxiety, potentially resulting in exacerbation of symptoms if the antipsychotic dosage is increased 56. Although related to DRBA exposure, akathisia responds poorly to anticholinergics. The lack of supportive evidence for anticholinergic medication in patients with akathisia is documented in a 2006 Cochrane review 57. Included studies on the occurrence of withdrawal symptoms after abrupt antipsychotic discontinuation. Where assumptions had to be made regarding people lost to follow‐up (see Dealing with missing data) we compared the findings when we used our assumption with ‘completer’ data only.

In my experience, hypnotherapy has not been helpful in long-term benzodiazepine users. Your doctor may have views on whether it is appropriate for you to stop your benzodiazepines. Some doctors, particularly in the US, believe that long-term benzodiazepines are indicated for some anxiety, panic and phobic disorders and some psychiatric conditions. However, medical opinions differ and, even if complete withdrawal is not advised, it may be beneficial to reduce the dosage or to take intermittent courses with benzodiazepine-free intervals.

  • DIMDs related to antipsychotic exposure include DIP, akathisia, dystonia, and TD.
  • Many people being treated with antipsychotic medication also receive anticholinergic drugs to try to reduce some of these movement side‐effects.
  • It is necessary to take the tablets several times a day and many people experience a “mini-withdrawal”, sometimes a craving, between each dose.

Message from one of the participants of the Public and patient involvement consultation of service user perspectives on tardive dyskinesia research. This review is one in a series of Cochrane Reviews (see Table 4) evaluating treatments for antipsychotic‐induced TD, and is an update of a Cochrane Review first published in 1997 (Soares‐Weiser 1997). Thank you to Dr Richard Keefe (Duke University Medical Center) and Dr Marie-Cécile Bralet (CHI Clermont de l’Oise) for providing the English and French versions of the BACS. Dr Desmarais performed the literature search and wrote the first draft of the manuscript.
